Rng-tools cannot be installed

On a freshly flashed AGX Orin, with L4T R34.1.1 :

sudo apt install rng-tools reveals a conflict with nvidia-l4t-init.

default config file installed by nvidia-l4t-init prevents rng-tools from being installed.

$ sudo apt install rng-tools

 trying to overwrite '/etc/default/rng-tools', which is also in package nvidia-l4t-init 34.1.1-20220516211757

I am unsure which package is more appropriate to contain the default config file.
The only difference is HRNGDEVICE=/dev/urandom, enabled in the nvidia version, commented in the ubuntu version.

You can use dpkg to force overwrite the file, and then modify the default config back to how nvidia had it, but it seems to break later jetpack updates when nvidia-l4t-init needs to be updated.

Is there a better way for nvidia to impose their configuration?

Try below command.

sudo apt-get install -y rng-tools5
